Prepare grill to medium-high heat. Combine first 4 ingredients in a small bowl; stir well with a whisk. Thread artichoke hearts, eggplant, and tomatoes alternately onto each of 8 (10-inch) skewers. Place skewers on grill rack coated with cooking spray; grill 6 minutes or until tender, turning frequently. Place skewers on a platter; brush with juice mixture. Sprinkle with salt and pepper. Serve with lemon wedges, if desired. We use frozen artichoke hearts for convenience. Use fresh baby artichoke hearts, if you like, but blanch them first in boiling water with lemon juice for eight minutes or just until barely tender; quarter and arrange on skewers.
